Abstract
A twin-clutch device is provided that overcomes problems relating to a releasing property, a start property and a phase shift between clutch disks. The device includes first and second clutch disk assemblies 5 and 6, an intermediate plate 7, a clutch cover assembly 9, strap plates 16 and control mechanism. The intermediate plate 7 is disposed between the two clutch disk assemblies. The clutch cover assembly 9 has a pressure plate 17 and a diaphragm spring 18. The strap plates 16 bias the pressure plate 17 away from the flywheel 2. The control unit operates in a clutch switching operation to move the intermediate plate 7 at a slower speed than the pressure plate 17 upon start of movement of the pressure plate 17, and then to move both the intermediate plate 7 and the pressure plate 17 in synchronization with each other after the pressure plate 17 moves a distance corresponding to a predetermined stroke.
